What is the difference between quantum computers and quantum accelerators?

Click For Summary
Quantum computers and particle accelerators serve fundamentally different purposes. Quantum computers manipulate quantum bits (qubits) to perform calculations, while particle accelerators are designed to accelerate and collide particles for experimental purposes. The production of particles in quantum computing involves entanglement, which is not a factor in particle acceleration. The term "quantum accelerator" is not widely recognized, leading to confusion with classical computing accelerators. Understanding these distinctions is crucial for grasping the unique functionalities of each technology.

Hello. Could you please explain to me what the difference is between quantum computers and quantum accelerators?

There is no such thing as a quantum accelerator. If you mean a particle accelerator, then the two things are completely different. In a quantum computer you have to produce particles in a certain way, which you will also have to do in an accelerator, but not in an entangled way. And here end the similarities. An accelerator accelerates and smashes those particles, a quantum computer "measures" them. I don't know how they actually manufactured quantum computers, but Wikipedia should be of help here.

This link maybe help you (but, I am afraid, not me). Wikipedia does not contain subjects about quantum accelerator .

Careful: at a place like Physics Forum, many folks will take the term "accelerator" to mean "particle accelerator".

Some with background in (classical) computing will be familiar with the term "accelerator" in context of classical computing. From Wikipedia:

I suspect (but have not checked) that a quantum computer accelerator plays a somewhat similar role.

Thank you.
 

Thread 'Two equivalent statements of time reversal symmetric Hamiltonian'

Time reversal invariant Hamiltonians must satisfy ##[H,\Theta]=0## where ##\Theta## is time reversal operator. However, in some texts (for example see Many-body Quantum Theory in Condensed Matter Physics an introduction, HENRIK BRUUS and KARSTEN FLENSBERG, Corrected version: 14 January 2016, section 7.1.4) the time reversal invariant condition is introduced as ##H=H^*##. How these two conditions are identical?
